For the intravenous TXA group, administration will follow the current protocol at London Health Sciences Centre (LHSC), where a standard dose of 20 mg/kg will be given to the patient prior to skin incision. For the topical group, a standard dose of 1.5 grams will be given as per the best current evidence in total knee arthroplasty. The latter will be administered at the end of the procedure; the solution will bathe the operative field for 5 minutes during arthrotomy closure, with the final prosthetic components in situ.
